Log Bloomerang donor conversations once, on the right record

**Objective:** Record that a conversation took place with `{constituent-name}`, writing it to their record as an interaction, and open a follow up task if one is needed. What was said is in `{contact-summary}`, over the channel `{channel}` (default Phone).

**Step 1: Resolve the constituent before writing anything**

Call `bloomerang-get-constituent` with `full-name.contains` set to `{constituent-name}`. If more than one record comes back, list each with full name, primary email, city and account number, then stop and ask which is meant. If nothing comes back, retry once with the surname only, and if it still finds nothing, say so and stop. Never create a constituent to make this prompt work.

Keep the id. It is the account-id for every write below.

**Step 2: Check this is not already logged**

Call `bloomerang-get-interaction` with that account-id and `date.from` set to seven days ago. If an interaction already exists with the same channel and a materially similar subject, show it and ask whether to log a second one before going further.

**Step 3: Confirm what will be written**

Show the exact interaction you intend to create: the constituent name and account number, the date, the channel, the purpose, a subject line of at most eight words drawn from `{contact-summary}`, whether it was inbound, and the note body.

Wait for the user to confirm. Do not write on an assumed yes.

**Step 4: Write it**

Call `bloomerang-add-interaction` once, with the confirmed values. Once only. If it fails, report the error and stop; do not retry with altered values in the hope of getting it through.

**Step 5: Follow up, only if one is warranted**

If `{contact-summary}` describes something that has to happen next, propose a task: subject, purpose, channel, due date and owner. Show it, wait for a second confirmation, then call `bloomerang-add-task` once with the same account-id.

If nothing was promised, do not create a task.

**Step 6: Confirm it landed**

Call `bloomerang-get-interaction` with the account-id and today as `date.from`, and report the stored record back with its id. If a task was created, call `bloomerang-get-task` with the account-id and confirm it the same way.

**Rules and Guidelines:**

* The only tools permitted to write here are `bloomerang-add-interaction` and `bloomerang-add-task`, each at most once, each after its own explicit confirmation.
* Do not call `bloomerang-update-constituent`, `bloomerang-add-note`, `bloomerang-add-constituent`, or any other tool whose name starts with bloomerang-add- or bloomerang-update-. If the conversation revealed a new email address or phone number, report it for someone to apply and leave the record alone.
* Do not invent detail. Anything not present in `{contact-summary}` does not go in the note.
* Write the note in plain past tense, naming what was discussed and what was agreed.

**Validation:**

* If `{contact-summary}` is empty, ask what was discussed. Do not log an empty interaction.
* If `{channel}` is not one of the values the existing interactions use, ask rather than guessing.
